A novel risk-based decision-making paradigm
Morgado, Pedro; Marques, Fernanda; Silva, Miguel; Sousa, Nuno; Cerqueira, Jo??oThis paper presents a novel rodent decision-making task that explores uncertainty, independently of expectation and predictability. Using a 5-hole operating box, adult male Wistar rats were given choices between a small certain (safe) food reward and a large uncertain (risk) food reward. We found that animals strongly preferred the safe option when it had a fixed position or was cued with a light in a random pl...
Differential impact of chronic stress along the hippocampal dorsal???ventral axis
Pinto, V??tor; Costa, Jo??o Carlos Cardoso; Morgado, Pedro; Mota, Cristina de F??tima Sousa da; Miranda, A.; Bravo, Ana Francisca Rodrigues VazPublished online 06 February 2014 ; Stress impacts differently in distinct brain regions. However, so far few studies have focused on the differential responses triggered by stressful stimuli on the intrinsic functional heterogeneity of the hippocampal axis. In this study, we assessed the functional and structural alterations caused by exposure to a chronic unpredictable stress (CUS) paradigm on the dorsal-ven...
Clinical, physical and lifestyle variables and relationship with cognition and ...
Santos, Nadine Correia; Costa, Patr??cio Soares; Cunha, Pedro Miguel Guimar??es Marques da; Nunes, Carlos Portugal; Amorim, Liliana; Cotter, JorgeIt is relevant to unravel the factors that may mediate the cognitive decline observed during aging. Previous reports indicate that education has a positive influence on cognitive performance, while age, female gender and, especially, depressed mood were associated with poorer performances across multiple cognitive dimensions (memory and general executive function). Herein, the present study aimed to characteriz...
Telephone-based screening tools for mild cognitive impairment and dementia in a...
Castanho, Teresa C.; Amorim, Liliana; Zihl, Joseph; Palha, Joana Almeida; Sousa, Nuno; Santos, Nadine CorreiaThe decline of cognitive function in old age is a great challenge for modern society. The simultaneous increase in dementia and other neurodegenerative diseases justifies a growing need for accurate and valid cognitive assessment instruments. Although in-person testing is considered the most effective and preferred administration mode of assessment, it can pose not only a research difficulty in reaching large a...

Sousa, Nuno J. Vasconcelos Albuquerque eAdministrative law had an important development since the end of World War II and has changed deeply. This study explains these modifications.
Stress affects theta activity in limbic networks and impairs novelty-induced ex...
Jacinto, Luís; Reis, Joana; Dias, Nuno S.; Cerqueira, João J.; Correia, José Higino; Sousa, NunoExposure to a novel environment triggers the response of several brain areas that regulate emotional behaviors. Here, we studied theta oscillations within the hippocampus (HPC)-amygdala (AMY)-medial prefrontal cortex (mPFC) network in exploration of a novel environment and subsequent familiarization through repeated exposures to that same environment; in addition, we assessed how concomitant stress exposure cou...
Chronic stress disrupts neural coherence between cortico-limbic structures
Dias, Nuno S.; Oliveira, João Filipe; Correia, Mariana; Gama-Pereira, Filipa; Sardinha, Vanessa Morais; Lima, Ana; Oliveira, Ana FilipaChronic stress impairs cognitive function, namely on tasks that rely on the integrity of cortico-limbic networks. To unravel the functional impact of progressive stress in cortico-limbic networks we measured neural activity and spectral coherences between the ventral hippocampus (vHIP) and the medial prefrontal cortex (mPFC) in rats subjected to short term stress (STS) and chronic unpredictable stress (CUS). CU...
